In the upcoming Last Laugh DLC, Hamill reprises his role as the Joker which he first first played in Batman: The Animated Series. (Hamill had initially portrayed corrupt businessman Ferris Boyle in the episode “Heart of Ice,” and was only offered the role of the Joker after the previous choice, Tim Curry, dropped out of the project.)

Hamill is joined by Adam Baldwin, who portrayed the Man of Steel for the DC Universe Animated Original Movie Superman: Doomsday released by Warner Premiere & Warner Bros. Animation in 2008. Another Batman: The Animated Series vet, Arleen Sorkin, returns as the Maid of Mischief, Harley Quinn.

The Last Laugh DLC released to Legendary subscribed members on June 14th, but the general release of the DLC will be available tomorrow, the 19th for the PC & PS3.
